VP1 — Camelina sativa

Summary

CSA03G031590 (VP1, also known as CsLEC2) on Camelina sativa chromosome 3 encodes a B3 DNA-binding domain transcription factor that localises to both the nucleus and cytoplasm. It is associated with positive regulation of auxin biosynthesis, seed oilbody biogenesis, embryo development ending in seed dormancy, flower development, photoperiodism, flowering, and responses to abscisic acid. The gene has been connected to seed weight, embryo lethal transition to heart stage arrest, embryonic maturation, desiccation intolerant seeds, abnormal embryos with trichomes on cotyledons, very limited somatic embryogenesis ability, triacylglycerol accumulation, trichome formation, seed storage protein accumulation, embryonic development, gibberellin biosynthesis, seed oil biosynthesis, seed development, seed maturation program, oil accumulation, fatty acid metabolism, cell dedifferentiation, lateral root formation, triacylglycerol biosynthesis, cellular dedifferentiation, leaf oil accumulation, seed reserves, embryo development, embryonic identity, seed protein content, seed desiccation tolerance, vernalization memory, seed germination, seed sucrose content, seed oil content, and seed starch content. Studies of related genes in other species link the family to seed maturation, somatic embryogenesis, and triacylglycerol accumulation in leaves.
